What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1:Â Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2:Â Take We'll assume you're ok with this, but you can opt-out if you wish.Accept Read MorePrivacy & Cookies Policy Send to Email Address Your Name Your Email Address Cancel Post was not All right reserved AJ Design☰ MenuMath GeometryPhysics ForceFluid MechanicsFinanceLoan Calculator Percent Error Equations Calculator Math Physics Chemistry Biology Formulas Solving for percent error.

Approximate Value − Exact Value × 100% Exact Value Example: They forecast 20 mm of rain, but we really got 25 mm. 20 − 25 25 × 100% = −5 25 Therefore, always subtract the smaller value from the bigger. Without "Absolute Value" We can also use the formula without "Absolute Value". Sprache: Deutsch Herkunft der Inhalte: Deutschland EingeschrÃ¤nkter Modus: Aus Verlauf Hilfe Wird geladen...

Chemistry Homework Help Worked Chemistry Problems How To Calculate Percent Error Sample Percent Error Calculation Percent error is a common lab report calculation used to express the difference between a measured However, after he carefully measured his height a second time, he found his real height to be 5 feet.

Ex:-1/10 = -0.1 4 Find the absolute value of the result. so divide by the exact value and make it a percentage: 65/325 = 0.2 = 20% Percentage Error is all about comparing a guess or estimate to an exact value. It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. You measure the sides of the cube to find the volume and weigh it to find its mass.

Example: I estimated 260 people, but 325 came. 260 − 325 = −65, ignore the "−" sign, so my error is 65 "Percentage Error": show the error as a percent of This is also called the accepted, experimental or true value.Note due to the absolute value in the actual equation (above) there are two value.
